IBU'ITIENG GAUGE.

Application filed December 20, 1923. Serial No. 681,877.

To aZ whom it may concern:

Be it known that I, CLARK E. VVooDLnY, a citizen of the United States, and a resident of Los Angeles, in the county ofLos Angeles and State of California, have invented certain new and useful Improvements in Butting Gauges, of which the following is a specification.

My invention relates to and has for its purpose the provision of a butting gauge which, in its application to a door, renders the chiseling of the recessesin the door for the reception of the butt hinges with or;- treme accuracy as to width, length and depth, whereby the proper'fitting of the hinge leaves to the door can be readily effected.

I will describe only one form of butting gauge embodying my invention and will then point out the novel features thereof in claims.

In the accompanying drawings Figure 1 is a view showing in perspective a portion of a door having applied thereto one form of butting gauge embodying my invention Figure 2 is a view similar to Figure 1, showing in side elevation the butting gauge in applied position; and

Figure 3 is a sectional View taken on the line 3-3 of Figure 7 Referring specifically to the drawings, in which similar reference characters refer to similar parts, my invention in its present embodiment comprises a plate of suitable material bent to provide a flat intermediate portion and the edge portions 16 and 17 arranged in parallelism and disposed substantially at right angles to the intermediate portion 15'. A plate so bent has the cross sectional contour of a Li, so that it can be applied to the butting edge of a door in the manner shown in the drawings.

The intermediate portion 15 is formed with an opening 18 which extends into the edge portion 16 for ashort distauce, as clearly illustrated in Figure 1. This opening 18 is of substantially rectangular form and outline so as to provide a gauging edge 19 for determining the width of a recess to be formed, end gauging edges 20 for determining the length of the recess, and a gauging edge 21 for determining the depth of the recess. As clearly shown in Figure 1., the edge portion 1 is recessed at the opposite ends of the gauging edge 21, as indiated at 22. These recesses 22 are formed to accommodate the cutting'edge of a chisel or other suitable tool so as to prevent injury thereto.

Substantially at the junction of the portion 17 and the intermediate portion 15 a slot 23 is'formed in the plate to slidably receive a'clamping member which, in the present instance, comprises a wedge 2% formed at one end with projections 25 to provide shoulders 26 for limiting the movement of the wedge in one direction through the slot. An operating flange 27 is formed on the other end of the wedge and is disposed at right angles thereto for the dual purpose of liiniting'the movement of the wedge through the slot in the other direction and to facilitate the movement of the wedge into clamping or non-clamping position.

In practice, the gauge is applied to the edge 28 of a door 29 so that the edge is re ceived between the parallel portions 16 and 17. NVhen applying the gauge the wed 'e 24 occupies the released position shown-in dash lines in Figures 2 and 3, but after such application the wedge is forced inwardly to the solid line position shown, thereby securely retaining the gauge to the door edge.

Prior to the application of the gauge to the door, the location .ofthe recess to be formed in the edge of the door is determined by applying a leaf of the butt hinge to the door edge and marking on the door edge the ends of the hinge leaf. This having been accomplished, the gauge can now be applied to the door edge with the marks on the door edge determining the position of the ganging edges 20. lVith the gauge securely clamped to the door, the recess may now he formed by the employment of a chisel or other suitable tool in the usual manner, the several gauging edges determining the depth, width and length of the recess formed.

Although I have herein shown and described only one form of butting gauge embodyig my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.

hat is claimed is:

1. A butting gauge comprising a member, -,U-shaped in cross section and provided with an: opening, and a wedge movable through the member and cooperating with the neinher for securing the latter to the edge of a door, said Wedge being permanently attached to themen'iber.

2. A butting gauge comprising a plate, U-shaped in cross section and formed With an openin which extends from the intermediate portion into one of the parallclportions, and means for removabl clamping the plate to the edge of a door.

3. A butting gauge comprising a plate, U-shaped in cross section and: formed with an opening which extends from the intermediate portion intoone ot' the parallel portions, said plate having notches at the ends of that portion of the opening extending into the parallel portions, and means for removably securing the plate to the edge of adoor.

l. A butting gauge comprising a plate, U-shaped in cross section and "formed with an opening which extends from the intermediate portion into one of the parallel portions and a slot, and means movable in said slot for removably securing the plate to the edge 01"? a door.

5. A. butting gauge con'iprising a member substantially U-shaped in cross section and having an opening therein and a slot spaced from-the opening, and amember slidable in theslot to clamp the first member'to the edge of a door. 7

6. A buttinggauge comprising a member U-shaped in cross section and having an opening therein and a slot spaced from the opening, and a wedge slidable in the slot, an operating lip on one end of the Wedge, and shoulders on the other end of the wedge, the lip and shoulders servingto retain the Wedge against displacement from the slot.

7. A butting gauge comprising a member having a gauging opening and a second opening and a-Wedge movable inthe second said opening for securing themember to the edge ot'a door.

8. As a new article oi manufacture,a'but ting gauge comprising a member bent from a single sheet of metal into-U.-form to provide parallel portionsa-nd a connecting portion having a gauging opening extending into one'ot the} parallel portions, and means for clamping the member to the edge of a door. 7
